Warlock, Warrior or WW Monk from the PTR?

So I am actually returning from a long break and going to focus a bit on PVE and PVP.

I've played a monk till around level 15 before taking a break. This was way back in October just immediately after MoP launched.

I am looking for a class that I've never played before. And all these 3 fall in that category including shamans and rogues. But I don't really find the latter 2 any interesting. Which one of the classes are looking good moving ahead in 5.2?

I would love to download the PTR but my internet speed is kinda crappy and it would take me a day or two. So its either a Warrior, Lock or Windwalker Monk.
